Based on the replies above this is definitely a similar to a investment bank except it accepts retail investors. Trading commodities such as gold and crude oil can generate a lot of income per price fluctuation. In a single day the price of gold can move up and down by more than a 1000 points. Now imagine if you trade $100 per point that would become:
$100x1000=$100,000.
And that fluctuation will happen in only less than an hour.
For currencies, say EURUSD, if it moves 200 pips it setting per pip value @ 100:
$100x200=$20,000
In a single hour. But I bet the traders doing the actual trading get more money out of that compared to what they are giving out.
Anyway, the returns are good, but if I were to choose if I had that amount of cash to invest, I would rather learn to trade and gain new skills. IMO once you become a trader and then a manager you can then start your own business this way. Of course, the safest bet would be traditional business, it's easier because it only requires a little planning and some manual labor. But the returns are well... very proportional.
